For decent speed, in 120 class bullets (and the 100 gr ttsx w/ 8208xbr) I think the best temp stability powders for you would be either AR Comp and/or Xbr, now these are not Varget/H4350 stable powders but do have somewhere like 0.6 ft/s/degF sensitivities.
If your barrel likes the sst it's a good shooter, also the 120 gold dot, and 120 Nosler BT. these have .500-.460 type BC's to give you some distance for western hunts... I also have a 100 ttsx load (0.359 BC) at ~2650 that's good for maybe 250-275 yds for deer, using Xbr.
As always, work up and use a chrony to find your sweet spots MV-wise.
If you don't have the Grendel Handbooks (vol 1 and 2) then go to AR15 buildbox section of the vendor part of this forum, order them, they will give you lots of info as well as lots of load data to pick from.
There are some western hunters on here, maybe they have some advice for you also! I love the west and have hunted there some but (lately) not firing any shots....
For the 129 Ablr and adequate distance, the only powder I personally have tried is the CFE... fwiw. but it is a great bullet.
